I take notes on just about anything and everything. I call it a “journal” but it’s not the foo foo style or the feel-good stuff that other people do when journaling.
The most important thing I write down (in Bear Notes) is stuff relating to my business. If I learn how to do something I make a note just for that in case I ever need to do it again. Or what my competition is doing wrong and ways I can do better. Or plans of action I need to take.
I even take notes on how to load my printer a certain way for the thing I do twice that involves that printer.
I also take a lot of screenshots and save them in continuous section where I create a new journal every week. It gives my life a timeline and makes finding things easier. To refer back to older notes I use my timestamp that I wrote about here. I also have a Keyboard Maestro command that when I type certain letters grabs the url of Chrome since that is where I get most of the screenshots from. For the full page, I use Vivaldi browser since it has a screenshot tool that can capture the page in full to PNG.
The best part is my rants or stupid things I come across on the internet. I even put funny pictures for when I come back later to read.
About the only thing I regret is not starting sooner. It would have been nice to reflect back on my thoughts when my father was still alive or my old horrible job and the constant stupid things that would happen. If anything its great therapy.
I would add that using something like TextExpander or Keyboard Maestro really helps keep things organized and easier to find. I also like using Bear Notes because its simple and allows me to put as many pictures, voice memos, PDFs, or whatever attachments I want in the notes. I also recommend backing up the notes to another location as I’ve found its easy to get many of them after a while and Bear Notes has a great export as HTML feature that keeps the formatting and plus Spotlight can index those so makes finding old timestamps so much easier.
